Abstract
Description
Technical Field
[0001] The utility model relates to the field of fixed buildings, in particular to an assembled wall column connection structure. Background Art
[0002] For fixed buildings, walls and columns are their basic components. In traditional technology, concrete columns are cast on site, and walls are made by stacking. The walls and concrete columns are bonded by mortar. The problem with this traditional wall-column connection structure is that the connection strength between the wall and the concrete column is not high. The entire concrete column is a cast-in-place component. The workload of on-site casting is relatively large, which is easy to cause environmental pollution. In addition, it is necessary to tie the steel cage on site and wait for the concrete column to solidify, which takes a long construction period.
[0003] In the prior art, there is an assembled wall column connection structure, that is, precast concrete columns and precast concrete wall panels are manufactured in advance in a factory, and the precast concrete columns and precast concrete wall panels are assembled at the construction site. Compared with the traditional on-site casting, this assembled wall column connection structure has less on-site casting work, high construction efficiency and short construction period. However, there is still a problem that the connection strength between the precast concrete columns and the precast concrete wall panels cannot be guaranteed. Utility Model Content
[0004] The utility model aims to provide an assembled wall column connection structure to solve the technical problem of insufficient connection strength between precast concrete columns and precast concrete wall panels in the prior art.

The prefabricated wall column connection structure also includes a post-cast concrete body cast on the periphery of the exposed longitudinal reinforcement, the exposed ends of the stirrups and the exposed ends of the transverse reinforcement.
[0007] Furthermore, the exposed ends of the transverse reinforcement are connected with the exposed ends of the corresponding stirrups and the exposed longitudinal reinforcement by tying wires.
[0008] Furthermore, the left and right ends of the upper end head are convex ends of the upper end head that protrude outward from the left and right sides of the upper end of the middle concrete, the left and right ends of the lower end head are convex ends of the lower end head that protrude outward from the left and right sides of the lower end of the middle concrete, the upper and lower ends of the post-cast concrete are respectively connected to the convex end of the upper end head and the convex end of the lower end head, and the left and right ends of the post-cast concrete are respectively connected to the opposite sides of the middle concrete and the wall panel concrete.
